Traditionally, engineers relied on languages such as FORTRAN and C to solve technical problems, but these often required complex coding and lengthy debugging. MATLAB, short for MATrix LABoratory, was developed to simplify these processes by integrating computation, visualisation, and programming in one environment. Its interactive nature and powerful built-in routines make it a standard tool for modern engineering practice, particularly in aerospace applications where matrix operations and data analysis are central.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS The aim of this Series is to introduce you to the fundamental features of MATLAB and to equip you with the skills needed to use it as a calculator, a programming workspace, and a versatile tool for aerospace engineering computations. We shall commence this Series by examining the origins and role of MATLAB in aerospace engineering. Next, we will explore how MATLAB functions as a calculator and workspace environment, focusing on scalar and matrix operations, variables, and simple scripts. Following that, we will consider MATLAB’s data structures and interactive features, including arrays, editing tools, and object-oriented programming support. Finally, we will wrap up by looking at MATLAB’s applied contexts, particularly its toolboxes for signal processing, control theory, symbolic computation, simulation, and optimisation. This sequential flow will provide you with a strong foundation for using MATLAB effectively in your studies and future engineering practice.

These packages were designed for solving linear systems and eigenvalue problems, which are central to engineering and scientific applications. MATLAB integrates computation, visualisation, and programming in a single environment, making it a versatile tool for both teaching and research. Fill in the blank: MATLAB was originally developed to provide easy access to ______ and EISPACK projects.

Figure 1.1: Origins of MATLAB 1.1.2 Advantages of MATLAB over conventional languages One of the key advantages of MATLAB is its interactive system, where the basic data element is an array. An array is a structured collection of numbers or variables that does not require dimensioning before use. This feature allows engineers to perform calculations quickly without the need for complex coding. Unlike conventional languages such as C or FORTRAN, MATLAB provides built-in routines for a wide variety of computations and easy-to-use graphic commands for immediate visualisation of results. Fill in the blank: The basic data element in MATLAB is an ______, which does not require dimensioning.

Plate 1.1: MATLAB interactive environment 1.1.3 MATLAB as a standard tool in engineering MATLAB has become a standard tool in engineering education and practice because of its ability to integrate multiple functions seamlessly. It supports object-oriented programming, editing and debugging tools, and sophisticated data structures. Aerospace engineers use MATLAB to model systems, simulate flight dynamics, and optimise designs. Its toolboxes extend functionality into specialised areas such as signal processing, control theory, and symbolic computation, making it indispensable for meeting the demands of 21st-century industry. Fill in the blank: Aerospace engineers use MATLAB to model systems, simulate ______ dynamics, and optimise designs.

Mention two aerospace applications of MATLAB. 1.2 MATLAB As A Calculator And Workspace Environment 1.2.1 Scalar and matrix calculations MATLAB can be used as a powerful calculator, capable of handling both scalar and matrix operations. A scalar is a single numerical value, while a matrix is a rectangular array of numbers arranged in rows and columns. MATLAB was designed with matrices at its core, so operations such as addition, multiplication, and inversion are straightforward. For example, typing A + B in MATLAB will add two matrices of the same dimension. Fill in the blank: A scalar is a single ______ value, while a matrix is a rectangular array of numbers.

Figure 1.2: Scalar and matrix operations in MATLAB 1.2.2 Variables and elementary functions In MATLAB, a variable is a symbolic name that stores a value or an array. Variables allow you to reuse values without retyping them. For instance, assigning x = 5 means that MATLAB will store the number 5 under the name x. MATLAB also provides a wide range of elementary functions, such as sin, cos, exp, and log, which can be applied directly to scalars or matrices. These functions are essential for solving engineering problems involving trigonometry, exponential growth, or logarithmic relationships. Fill in the blank: In MATLAB, a variable is a symbolic ______ that stores a value or an array.

Plate 1.2: Variables and elementary functions in MATLAB 1.2.3 Scripts and simple functions A script in MATLAB is a file containing a sequence of commands that can be executed together. Scripts are useful for automating repetitive tasks and ensuring consistency in calculations. A function is a more advanced structure that accepts inputs and returns outputs. Functions are defined in separate files and allow engineers to design reusable solutions for complex problems. For example, a function can be written to calculate the lift force on an aircraft wing given parameters such as velocity, density, and wing area. Fill in the blank: A script is a file containing a sequence of ______ that can be executed together.
